@nlnetlabs The alternative that is on my list for Cloudfront is https://bunny.net, except that, like many non-US service providers, they have their own hyperscaler dependencies, such as Google Apps for email.
Also, unless something has changed fairly recently, 1Password depends entirely on AWS for all of their products and services, Google Apps for email, and so forth.
Tresorit seems to be all-in on Azure and M365. Communiteq seems to be running on Cloudflare + Digital Ocean.
So if this is anything more than a PR exercise, you will probably need to do a bit more work 😄
